Description
TECHNICAL FIELD
[0001] The present invention relates to a composition for conditioning keratin materials, in particular the skin, the scalp or the hair together with the scalp. The present invention also relates to a method for conditioning keratin materials, in particular the skin, the scalp or the hair together with the scalp using the composition of the present invention.
[0002] BACKGROUND
[0003] Keratin materials are widely present on the surface of the human body, such as the skin, the scalp and the hair. For a long time, many people have been seeking a fresh body surface in order to feel comfortable in daily life and work. Among them, many people are particularly concerned about the sticky / oily feeling. Therefore, various products have been developed to cope with the sticky or oily feeling of people.
[0004] Among the keratin materials of the body surface, the scalp is particularly prone to sebum. Various formulations have been developed for sticky or oily scalp, including those provided in a separate form, such as lotions, sprays, etc., and those incorporated into conventional products for the hair and / or the scalp, such as shampoos, leave-in and / or rinse-off conditioners.
[0005] Various conditioning compositions have been developed mainly for the hair, which are generally used to improve or restore the natural shine, luster, smoothness and softness of the hair. When used in the context of shampooing, the generally accepted method of conditioning the hair is shampooing the hair, then rinsing the hair, and then applying a conditioner composition, optionally followed by a second rinse.
[0006] Therefore, there is still a need in the art to develop new compositions for caring for the scalp, mainly, especially for the oily feeling. SUMMARY
[0007] Silica is known to be used in cosmetics, for example as a conventional filler, or as a substrate for absorbing lake dyes. Derivatives of silica and / or modified silica are also used. However, in the art, any effect of (modified) silica on addressing the oily state of keratin materials is unknown. Through intensive research, the inventors have surprisingly found that by using a specific modified silica (modified especially in terms of structure and chemical bonds) in a specific form, sebum migration on keratin materials, in particular on the scalp, can be effectively inhibited, and thus the oily feeling is inhibited.
[0008] Therefore, one subject of the present invention is a leave-in composition for conditioning keratin materials, comprising:
[0009] spherical particles of a lipophilic modified silica homogeneously dispersed in a medium / solvent;
[0010] at least one cationic polymer, and
[0011] at least one thickening agent.
[0012] The composition according to the application is in particular for conditioning keratin materials, for example, in particular for scalp care. Thus, the composition of the application can be in various forms, for example, a lotion, a cream, a spray, etc., to be applied directly to the scalp, to the skin or to the hair together with the scalp.
[0013] Embodiments of the application
[0014] Throughout the specification, including claims, the term "comprising" is to be read as synonymous with "including" and "containing", unless the context demands otherwise. Furthermore, throughout the specification, the expression "at least one" is equivalent to the expression "one or more".
[0015] Throughout the specification, including claims, embodiments which are expressed as comprising, including, containing etc. are to be interpreted as including the preferred embodiments which are expressed as consisting essentially of and the preferred embodiments which are expressed as consisting of.
[0016] Except in operating examples, or where otherwise indicated, all numbers concerning quantities of components and / or reaction conditions are to be understood as being modified in all instances by the term "about", with its conventional meaning in the art, for example within 10% of the indicated number (e.g. "about 10%" means 9% to 11% and "about 2%" means 1.8% to 2.2%).
[0017] Throughout the specification, including claims, "keratin materials" according to the application are the skin, the hair, the scalp, the eyelashes, the eyebrows, the body hair, the nails, the lips or the mucous membranes. Preferably, the keratin materials according to the application are locations which are susceptible to a sticky or greasy sensation, for example the scalp or the skin, and / or locations which are affected by a sticky or greasy sensation, for example the hair.
[0018] Throughout the specification, including claims, "care", "caring", etc. according to the application is to be understood as covering any means of caring for, maintaining or improving the condition of keratin materials, not only including conventional means of caring for keratin materials such as the skin or the scalp, but also including any means known to be useful for conditioning and / or cleansing keratin materials such as the hair or the scalp.
[0019] In the present application, amounts, parts and percentages are expressed on a weight basis, unless explicitly mentioned otherwise.
[0020] The present application relates to a composition for caring for keratin materials, comprising:
[0021] (A) spherical particles of a lipophilic modified silica which are homogeneously dispersed in a medium / solvent;
[0022] (B) at least one cationic polymer comprising a cationic cellulose polymer (B-1); and
[0023] (C) at least one thickening agent comprising a clean-feeling thickening agent (C-1) selected from a vinyl polymer.
[0024] Accordingly, the present application provides the use of spheroidal particles of lipophilically modified silica for the relief of the greasy feel on keratin materials on the body, in particular the scalp.

For example, one skilled in the art can determine whether a particle is spherical according to conventional knowledge. In particular, with respect to a given silica, one of ordinary skill in the art can distinguish a spherical shape from other shapes such as plates, rods, powders, strips, irregular shapes, and the like, as well as from amorphous analogs.
[0029] According to the present application, the silica is required to be in a "uniformly dispersed" state. For example, the formation of a dispersion, emulsion, solution, and the like having definitions and / or standards known in the art can represent the achievement of a "uniformly dispersed" state. Nonetheless, it should be understood that once one skilled in the art can determine that the state is significantly distinguished from a "non-uniformly dispersed" state, the state can be considered to substantially satisfy the "uniformly dispersed" state.
[0030] According to the present application, "lipophilically modified" silica means silica that has been subjected to a lipophilic modification. According to the present application, the lipophilic modification means any organic modification that enables the hydrophobic or lipophilic treatment of silica. For example, silica can be treated with a siloxane compound, such as a hydroxydimethylsiloxane (or other silane, such as a silazane, and the like), by which silanol groups on the surface of the silica and silanol groups of the siloxane compound are condensed. Among them, usable examples of "lipophilically modified" silica can be silylated silica and dimethylsilylated silica, such as silylated silica, for example, which can be available under the name TL-10 is a silylated silica from TOKUYAMA CORPORATION.

[0105] The amounts / concentrations of the ingredients in the compositions / formulations described below are expressed in weight % relative to the total weight of each composition / formulation.
[0106] Materials:
[0107] Silylated silica: available from TOKUYAMA CORPORATION under the trade name of TL-10, spherical particles of lipophilically modified silica;
[0108] Other materials not mentioned here are each commercially available.
[0109] Example 1
[0110] Preparation of compositions A and A':
[0111] Table 1
[0112]
[0113]
[0114] The above composition A was prepared according to methods known in the art.
[0115] 6 volunteers used the composition A and evaluated the fresh feeling brought by the composition A, compared to the control without the addition of component (B) or (C), the greasy feeling of the hair roots was less and the hair roots were visibly raised.
[0116] Example 2
[0117] The effect of the composition on sebum inhibition was determined with a sebum migration test, comprising the following steps:
[0118] Step 1 : The hair sample was washed with a standard shampoo DOP and washed with the test product according to known procedure RC-MCI-OIP-003B
[0119] Step 2: 100 μL of colored artificial sebum (red) was applied on a selected 3 cm area on the top region of the hair sample.
[0120] Step 3: The hair sample was hung on an iron stand under conditions of 30°C, 50% humidity.
[0121] Step 4: Take pictures of the hair swatches at 1 hour, 2 hours, 4 hours, 6 hours and 24 hours.
[0122] Step 5: Calculate the total sebum migration area at each time point using image analysis.
[0123] The results of the sebum migration are provided below:
[0124] Table 2
[0125]
[0126] For the sebum migration test, less sebum migration area means more inhibition of the oil. Thus, it is clearly seen that the contrast A' using lipophilic modified silica spherical particles evenly dispersed in the medium / solvent can bring high oil inhibition, which is reflected by the low sebum migration area. It is observed that even lower sebum migration area is produced when using the composition A.
[0127] Example 3
[0128] Six 25-45 year old volunteers were instructed to apply the composition A on the hair and scalp every day for 3 days. The scores for the stickiness or greasy feel before the application of the composition A were taken as the baseline and the scores for the stickiness or greasy feel after the application of the composition A were given every day and the average scores are shown in Table 3.
[0129] The volunteers gave scores for the greasy feel, wherein:
[0130] 0 means no change;
[0131] 1 means generally improved;
[0132] 2 means significantly improved; and
[0133] 3 means substantially no greasy feel.
[0134] The average scores of the six volunteers were taken as the immediate state, 24 hours and 48 hours and the average value per day was calculated. The average scores for the total of 3 days are provided in Table 3 below.
[0135] Table 3
[0136]
[0137] Note: For convenience, each average score in Table 3 is rounded to an integer.
[0138] Referring to Table 3, the higher the score, the less the stickiness or greasy feel. It is observed that the composition A shows very good and long term anti-stickiness or anti-greasy feel.
